Is Bluma worth using?
Yes for farming, no for damage — Bluma is the documented economy unit. Pro Game Guides calls her the 'obvious farm pick' (S); Beebom rates her A and 'best farming unit for infinite mode'. Her kills produce Training Data that raises whole-team income up to +30% per wave. She does not carry fights; she funds the units that do.
Tier placements are the two public tier lists (Pro Game Guides and Beebom), shown side by side because they disagree on several units — see the full tier list for how we handle conflicts.
